Constantly failing conversions

My MCEBuddy has completely stopped working properly. I keep getting errors that FFMPEG.exe has stopped working during conversions (see screenshot). Below is a link to log files and screenshot. This is getting really frustrating so any help would be greatly
appreciated!

Try downloading the latest build of ffmpeg from their website and replace it in the installation folder. If it's still happening then, and I suspect this even now, it's something else on your computer which is killing ffmpeg. Try disabling your
antivirus (they sometimes get messed up with their detection techniques and kill apps)
